渦街流量計有什么優點？西安華恒儀表為您詳細介紹：
What are the advantages of vortex flowmeters?Xi'an Huaheng Instrument for your detailed introduction:
1.兩線制、三線制都分別DCDC（DC1000V）隔離；
1.Two-wire system and three-wire system are separated by DCDC(DC1000V).
2.在測量工況體積流量時幾乎不受流體密度、壓力、溫度、粘度等參數的影響；
2.When measuring the volume flow rate under working conditions,it is almost independent of the parameters such as fluid density,pressure,temperature and viscosity.
3.支持4-20mA輸出、脈沖（當量）輸出、報警輸出、RS485通訊輸出；
3.Support 4-20 mA output,pulse(equivalent)output,alarm output,RS485 communication output;
4.儀表參數能長期穩定。本儀表采用壓電應力式傳感器，可靠性高，可在-25℃～+320℃的工作溫度范圍內工作；
4.Instrument parameters can be stable for a long time.The instrument adopts piezoelectric stress sensor,which has high reliability and can work in the range of-25~320~C.
5.應用范圍廣，蒸汽，氣體，液體等流體流量均可測量；
5.It has a wide range of applications.The flow rate of vapors,gases and liquids can be measured.
6.基于點陣顯示的人性化菜單和界面，配合明亮的背光，支持中文和英文兩種語言，適合各種客戶群；
6.Humanized menu and interface based on dot matrix display,with bright backlight,support Chinese and English,suitable for various customer groups;
7.支持溫度、壓力測量，方便氣體介質溫壓補償的需求；
7.Supporting temperature and pressure measurements to facilitate the requirement of temperature and pressure compensation for gas media;
8.支持流速換算顯示功能，方便現場看當前流速；
8.Supports the function of flow rate conversion and display,which is convenient for viewing the current flow rate on the spot.
9.支持分屏顯示功能，可以讓屏幕上放大顯示單個或兩個參數（溫度，壓力，工況、標況的流量和流速等）；
9.Supporting split-screen display function,it can enlarge and display single or two parameters(temperature,pressure,working condition,flow rate of standard condition,etc.)on the screen.
10.仿真輸出功能，支持4-20mA電流仿真、頻率輸出仿真，方便現場非實流調試；
10.The simulation output function supports 4-20mA current simulation and frequency output simulation,which is convenient for field non-real-current debugging.
11.無可動機械零件，因此可靠性高、維護量??；
11.There is no movable mechanical parts,so it has high reliability and low maintenance.
12.渦街流量計壓力損失小，量程范圍大，精度高；
12.Vortex flowmeter has small pressure loss,large measuring range and high accuracy.
